PW3365-20 Clamp on Power Logger

• monitoring of more than two dozen variables and parameters
• True RMS measurement
• harmonic analysis up to 13th order

Detailed Product Overview

The PW3365 Clamp-on Power Logger measures voltages and currents safely and efficiently without requiring direct contact with live conductors. Its innovative voltage clamp sensors attach directly to insulated wires, enabling fully non-intrusive measurements. Operating within a voltage range of 90 to 520 V and a current range of 50 mA to 5 kA at 50/60 Hz, it minimizes risks such as short circuits and accidental contact. This makes it an excellent choice for monitoring power consumption and demand in systems ranging from single-phase to 3-phase 4-wire configurations.

Its compact design allows the PW3365 to be installed easily in confined locations such as distribution boards, connection cabinets, or switchboards. The instrument delivers accurate readings and detailed measurement data to help identify inefficiencies and reduce energy losses. Equipped with an 8 GB SD memory card, it supports long-term stand-alone logging, making it well suited for energy audits, load studies, and equipment evaluations where extended data collection is required.

To perform measurements, the PW3365 requires AC current sensors with a BNC connector. These sensors are not included with the instrument and must be purchased separately. By choosing the appropriate sensor type, users can adapt the measurement range to their specific monitoring applications, ensuring high-precision and stable performance across different environments.

The PW3365 supports both load current and leak current logging, enabling comprehensive power analysis. Load current measurements help evaluate the consumption of machines, electrical panels, or entire facilities and assist in uncovering energy inefficiencies. Leak current logging identifies unintended leakage caused by insulation deterioration, wiring faults, or aging equipment. Monitoring leakage current is essential for preventing electrical hazards, reducing fire risks, and maintaining compliance with safety regulations. Together, these functions make the PW3365 a practical tool for detecting inefficiencies and emerging faults before they develop into serious issues.

The instrument includes the Z1008 AC adapter for powered operation when an outlet is available. If no mains supply is accessible, the optional PW9002 Battery Set can be mounted to the back of the unit and provides up to 3 hours of portable operation. These power options ensure dependable functionality in both fixed installations and mobile field work.

Designed for energy consultants, facility managers, and service engineers, the PW3365 offers a safe, reliable, and user-friendly solution for energy monitoring. Its compact footprint supports installation in tight spaces, while the non-contact voltage clamps simplify setup and eliminate the risk of creating short circuits. The device supports real-time monitoring via LAN and integrates seamlessly with the free HIOKI Gennect One PC software for continuous power management.

Delivering all essential measurements for single-phase through 3-phase 4-wire systems, the PW3365 provides accurate, dependable insights suitable for both short-term audits and continuous long-term monitoring, helping users improve operational efficiency and achieve meaningful energy savings.
